采用水热法制备了纯相Tb(OH)_3纳米棒,并以Tb(OH)_3纳米棒为掺杂剂制备了Tb~(3+):SiO_2光转换功能薄膜。研究了反应温度、离子浓度以及pH值对Tb(OH)_3纳米棒形貌结构的影响,同时研究了Tb(OH)_3纳米棒和Tb~(3+):SiO_2薄膜的发光性能。结果表明:在pH值为9.0,水热温度为180℃,离子浓度为0.25mol/L时合成的纳米棒在492,543,584和621nm处都有明显的荧光发射;而且,与其他样品相比,其荧光强度最强。在紫外光激发下,Tb~(3+):SiO_2薄膜在表现出Tb~(3+)特征发光的同时,也在400~480nm处表现出较强的宽带蓝紫光发射。
Single phase Tb(OH)3 nanorods were prepared by the hydrothermal method, and Tb3+:SiO2 photoluminescent films were fabricated using the Tb(OH)3 nanorods as dopant. The effects of reaction temperature, ion concentration and pH value on the morphology of the Tb(OH)3 nanorods were studied. The luminescence properties of the Tb(OH)3 nanorods and the Tb3+:SiO2 films were also studied. The results indicate that, when the reaction temperature is 180 ℃,ion concentration is 0.25 mol/L and pH value is 9.0, the prepare...
